  • [x86-64] No 2160p on JVC Projector

    Quote from chewitt

    It's interesting that N150 might also be impacted with that issue, I'd previously believed it was limited to N100.

    I probably need to order a box to do some testing and experimentation with, although the current queue of stuff on my desk is getting long and I'm probably lying to myself about available free time.

    I still have my AM6B+ that's working great with CoreElec, and so would be happy to mail you this NUC as a long-term loaner to play with if it helps (though I hear you on time constraints). I'd been hoping the LibreElec route with an Intel NUC would have been easier and with less hassle factor, which is why I went down the rabbit hole. Since that's not the case, no harm on my side to be without the N150 NUC for some months. PM me if interested, but no pressure!

    Finally had a chance to do a few changes and test. With some AI support, enabled the audio dropout script fix to be persistent. Verified it stuck across reboots upstairs (office with PC monitor), then took the box down to the theater. Interestingly I had the same weird resolution change issue. Blue screen, projector HDMI status message stated something along the lines of “out of range”, etc. NUC would still respond to power commands from remote, so I powered down and back up again, and this time was able to get further with a weird 768xsomething resolution, very blocky and jagged. Kodi asked if I wanted to keep that resolution, replied no - then it tried again, and selected 2160p/60 Hz which I accepted.

    So, outside of the audio dropout issue, there does appear to be a weird issue with resolution changes that isn’t fixed by the Adjust refresh/white list changes. To try and address, I then implemented your suggestion of adding video=HDMI-A-1:1920x1080M@60 to kernel boot params in syslinux.cfg. THAT at least seems to fix the problem of the box being able to consistently boot without resolution refresh issues.

    On to the semi-good news! The audio dropout script fix shared above for the N100 also seems to work for the N150 NUC I have. I could only get it to “stick” to my primary HDMI port, but as long as I’m using that one (closest to power plug), pass through audio just works as expected.

    So, to sum up - I think I finally have an Intel N150 based NUC that can consistently boot into Kodi without display issues, and pass through audio works perfectly. While that works for me now, I’m sure others will have problems in the future. I appreciate all the help you were able to give me, and if there’s anything I can do to help test or explore the issues described above, please just let me know. Happy to help as I can!

    Thanks again!

    I've tried running the script located in post 46 of this thread:

    Post

    RE: Intel Alder Lake 2160p @ 23.976 Hz passthrough HD Audio dropouts (i7-1270p/N100)

    After some more help and this time from jernej . Thank you.

    I have now a script to fix the audio problem for any LE11/12 without extra binary. The same script works on LE11 or 12.
    wget https://raw.githubusercontent.com/sky42src/LibreELEC.tv/11.80.5-240204/projects/Generic/filesystem/usr/bin/intel-gpu-max-10-bit.sh && chmod +x intel-gpu-max-10-bit.sh && ./intel-gpu-max-10-bit.sh

    I opened a pull request to make the helper script part of official LE.

    As far as I can tell, this is the same fix you mention above for the N100 issues. Will test and update with results.

    One key question - are these script's changes persistent? Or do they need to be reapplied somehow every time the box power cycles or reboots?

  • Intel Alder Lake 2160p @ 23.976 Hz passthrough HD Audio dropouts (i7-1270p/N100)

    Hi all - I've run this script on my N150 based GMKtec NUC and will be testing. However, I ran it when connected to an office PC monitor, and will need to turn the box off to move it down to the theater to test. Are the changes from this script persistant?

  • [x86-64] No 2160p on JVC Projector

    Ok, some good progress, but new oddities as well. I checked, and Adjust Refresh was not enabled. I turned that on, but just for start/stopping videos so that I could leave the UI at 1080x1920p. I also turned on the whitelist, and enabled the following per the wiki recommendation:

    3840x2160 @ 60/59.94/50/30/29.97/25/24/23.976
    1920x1080 @ 60/59.94/50/24/23.976

    Once done, the 4K videos launch and play as expected. However, now I get an occasional audio pause or distortion every 10-15 seconds. This is for streaming passthrough audio, so I am guessing it *might* be because I'm playing from a network share directly, and not via Plex and its presumable streaming/buffering capabilities?

    Hoping to get some feedback on that new issue, I turned on logging and rebooted the NUC. Unfortunately, the NUC would no longer boot into Kodi, and instead showed the same blue screen I saw earlier (before I enabled the Adjust Refresh and whitelist resolution recommendations). The first time I saw the NUC bios screen and briefly saw the LibreElec logo, but then had to hard shutdown the NUC (held down power button for 5+ seconds) to try again. Afterward, didn't even see the LibreElec logo upon powering up - only saw the bios screen briefly.

    So, I powered the NUC down and brought it back up to the PC monitor and plugged back in. And lo and behold, somehow the Video UI resolution had been set back to 2160p (definitely not by me), which at first seemed to help explain the blue screen - *but* then I realized I had previously set the Adjust Refresh on (for starting/stopping videos) and the Whitelist refresh settings, so in theory it shouldn't matter. I checked those latter settings again, and verified they were still set and had not automagically changed from under me (like the UI resolution setting did).

    The likely long log can be found at https://paste.libreelec.tv/dynamic-crab.log

    In summary:
    1. would love input on what the audio issue might be (if possible)
    2. am mystified as to the unexpected settings UI resolution change to 2160p (first of all)
    3. and, surprised why it wouldn't work with that resolution since the videos seemed to work with the Display Refresh and Whitelist changes? Perhaps this last one is because Adjust Refresh is on for only starting/stopping videos, and not called on first booting into Kodi?

    Thanks again for all of the help!

    Done. I had issues mapping an SMB share, but NFS worked fine, so I used that.

    To try and clean things up even more, I reset LibreElec to factory defaults (which also removed the Plex plugin - PM4K).

    Test:

    1. Set UI to 1920x1080P when connected to my PC monitor (so I could see UI)
    2. Moved NUC down to theater, and connected to Marantz/Projector HDMI chain.
    3. Powered on, verified I could view UI at 1080P.
    4. Turned on logging.
    5. Launched 4K movie via Videos view - played, but at 1080p (as verified by projector popup)
    6. Submitted log: https://paste.libreelec.tv/just-goblin.log

    I can find the playback in the log, so I think it worked. Note that I did *not* try to set the Kodi resolution setting again this time, just to keep things cleaner. I only tried playing the 4K video as suggested. Thanks again!

  • [x86-64] No 2160p on JVC Projector

    Thank you for those clear instructions!

    I first turned on logging, then tried to change from 1080p to 2160p, both 60 and 59.94 Hz. That log is:
    https://paste.libreelec.tv/enormous-dory.log

    I realized afterward that I had forgotten to reboot the machine/restart Kodi. So I did that, and this time:

    1. Verified 1080p UI was showing
    2. Launched 4k movie, verified it played (though downsampled to 1080p)
    3. Attempted change to 2160p in settings (leaving 60 Hz already selected) - failed
    4. Changed Hz to 59.94 (succeeded)
    5. Attempted change to 2160p again, failed

    This second log is: https://paste.libreelec.tv/suitable-quail.log

    Hope this helps!

    Update:

    Verified that the NUC works at 1080p for both UI and video playback, and in fact will play 4K videos (though reduced to 1080p during playback). This is for both 60 and 59.94 Hz. I had hoped that playing a 4K video would at least trigger 4K video playback, but no luck (just got the same blank screen for a few seconds before falling back to 1080p). Also removed the NUC and replaced the AM6B+ Android device with Kodi and played the same video, same high-end HDMI cable and verified it works fine.

    At this point I’m quite sure it’s not the HDMI cable, and am not sure what else I can check. Projector is JVC DLA-NX7, running through a Marantz AV8802 preamp, and I’ve never had issues with color output/input. Is there a specific test or log I can collect that might help? Happy to chase down whatever else I can if it’s helpful, with thanks!

  • [x86-64] No 2160p on JVC Projector

    Thank you both! I am away from home right now, so I can’t test further, but when I get back I will try setting the Kodi UI to 1080p and then try to launch a few 4K video files. I “know” (or am pretty highly certain) that this is not a problem with HDMI cable or the receiver or projector capabilities as 1) it’s a high-end home theater that has five HDMI inputs through the chain, 2) the JVC projector/Marantz receiver combo has displayed 4K/60Hz content a million times (most recently through an Android AM6B+ running CoreElec, and finally, I tried the new NUC on three different HDMI cables (and then returned the previous devices to those inputs, which worked again). So, my best guess is that it’s an issue with LibreElec or perhaps the LSPCON chip mentioned earlier. Is there any sort of log or test I can do which might help diagnose the issue further?

  • [x86-64] No 2160p on JVC Projector

    Basically the title, but I just installed LibreElec Generic on the GMKtek G3 Plus. Everything is working fine, including displaying via HDMI to my PC monitor, and displaying through my JVC projector (connected to Marantz preamp) in the theater at 1080p. But as soon as I switch to 2160p the screen simply blanks out. I wait a few seconds, and it returns back to the earlier 1080p setting (as expected, since I was unable to confirm that 2160p was working). Does anyone have any ideas or suggestions? Bit of a bummer, as I was hoping to use this as the replacement for the Nvidia Shield Pro in the theater. Thank you!

  • Intel N150 w/LibreELEC Mini Review

    Quote from hdmkv

    Haven't used LE since the RPi3 days, but was curious to on a cheap GMKtec Intel N150, and did this YouTube review. It's a great performer if one doesn't need DV or HDR10+, or 3D MVC...
